Enter an input mask expression for a field. Normally, you enter either:
· Literal: A text formatting string enclosed in quotation marks.
· Function: A call to a user-defined function that returns the formatting string.
If you’re using a function, you can create your function from the Code page of the Visual FoxPro Project Manager.
An input mask is a property of fields and controls that restricts or dictates the format of user input. For example, an input mask such as (###) ###-#### restricts input to North American phone number format. An input mask operates character-by-character within a field
The input mask expression that you enter is used as the input mask property for the field when you put the field on a form with a VPM Enterprise data control.
If you need help understanding how to use the Visual FoxPro input mask property, see Visual FoxPro online Help.
